Drift mining is a method of accessing coal or minerals by creating nearly horizontal tunnels from the side of a hill or mountain. It's different from other mining types because miners can often walk straight into the mine, rather than going down a deep shaft. Think of it like entering a cave in the side of a hill. This approach is commonly used when coal seams are located in hilly or mountainous areas. It's generally considered more cost-effective and safer than some other mining methods because it doesn't require expensive lifting equipment and provides natural drainage.
